Just curious, how do you anticipate to get more lift from the cam lobe by grinding it? You can definitely achieve more duration by doing so, but in order to get more lift you need to add material to your cam lobe and then reshape it. Are you by chance TIG'ing the lobes and reshaping them, or are you just working with what you already have there?Scottie
I don't subscribe to this method myself , however, I am just experimenting and have no idea what the results will be. It might just be a classic fail.
I see. So... It's addition by subtraction.
I understand the concern and well I guess its too much of a risk with the brilliantly running motor that I have right now. I might give it a pass at the moment. However, just curious - isn't this the same thing which happen when we use the Cast iron engine cams in the AVL with the small base circle and which results in a higher lift on the same.
We're taking a little R&R and enjoying some time with family and friends. The shop will be closed December 9th, and will be back in the shop on Thursday, January 2nd, 2014.
Basically Jeff does the build-and-mill technique at Colt Cams. He TIG welds the cam lobes to build up the materials, then puts them in the CNC machine and completely redesigns to cam profile to what ever specs you'd like. I'm not sure what profile he used for his customers RE he did, but I do know he spent a bit of time researching it.Scottie
Hi Scottie, I tried reaching him however it seems he is on a holiday till next year. In any case , I think i maybe getting the S cams soon.Wish you a merry Christmas and a happy new year !!
The thing about the S Cams is that they have been tested and proven to work with the existing valve springs to overcome the inherent issues that were preventing higher revving. This is a big advantage.
That's why YOU need to talk to him and build the best Ace!Don't get me wrong, I'm not knocking the S Cams, they obviously totally rock! I'm just saying it would be nice to have a reliable performance supplier here in North America instead of everything coming from Europe. Those damn exchange rates are ridiculous.
Exchange rates KILL us Indians
